METHOD FOR PREPARING POLYURETHANE COATING AND ADHESIVE WITH ANTIBACTERIAL AND WATERPROOF PROPERTIES

摘要

A method for preparing a polyurethane coating and adhesive with antibacterial and waterproof properties comprises preparing a layered nanometer zirconium phosphate antibacterial body containing Ag ions and Zn ions, adding titanium trichloride and triethylaluminum as catalysts into polytetramethylene ether glycol and isophorone diisocyanate for performing a catalytic reaction so as to obtain polyurethane, and using the layered nanometer zirconium phosphate as an antibacterial agent and trimethylsilyl cyanide as a waterproof agent to modify the polyurethane, thereby obtaining the polyurethane coating and adhesive with antibacterial and waterproof properties, and involving the characteristic of environmental protection.
